This valve allows the toilet supply line to be connected to the fill valve without the use of a threaded nut, instead you can connect ⅜″ outer diameter water supply line directly into the quick water supply connector. The quick water supply connector includes an O-ring to provide a water tight connection. In some embodiments a metal ring holds the water supply line in the quick water supply connector. The exact specifications may vary.

Referring now more specifically to the drawings by numerals of reference, there is shown in FIGS. 1-4, various views of a fill valve 100.

FIG. 1 shows a fill valve 100 during an ‘in-use’ condition 50, according to an embodiment of the present disclosure. Here, the fill valve 100 may be beneficial for use by a user 40 to quickly connect a water supply to the fill valve 100. As illustrated, the fill valve 100 may include a fill valve body 110, a nut 120, a quick-connect fitting 130, and a water supply tube 140. The fill valve 100 may be for installation into a toilet tank 5 and for connection to a water supply of a building.

FIG. 2 shows the fill valve 100 of FIG. 1, according to an embodiment of the present disclosure. The fill valve body 110 may include an elongated length 112 configured for vertical orientation in the toilet tank 5 relative to a vertical axis 105. The fill valve body 110 may have a top end 114 and a bottom end 116 relative to the vertical axis 105, the bottom end 116 sized for insertion through a tank aperture 10 located in the toilet tank 5. Further, a nut 120 may be configured to mate with the bottom end 116 and secure the fill valve body 110 in the toilet tank 5 when the bottom end 116 is inserted through the tank aperture 10. Preferably, the bottom end 116 of the fill valve body 110 may include a threaded outer surface 118. In this embodiment, the nut 120 may include a threaded aperture 122 configured to mate with the threaded outer surface 118. Further, as shown, the fill valve body 110 may further include a refill tube 111 and a float device 113.

FIG. 3-4 are side views of the fill valve 100 of FIG. 1, according to an embodiment of the present disclosure. The quick-connect fitting 130 may be located at the bottom end 116 of the fill valve body 110. The quick-connect fitting 130 may include a quick-connect fitting body 132 that is preferably cylindrical. In one embodiment, the quick-connect fitting body 132 may be made from a plastic material. The quick-connect fitting body 132 may include an outer shell 133 defining an inner capacity 131 housing an O-ring 134 configured to create a water tight seal, and a collet 160. The collet 160 may be made from a plastic material. In addition, the fill valve 100 may include an O-ring guide 136 adjacent to the O-ring 134. In one embodiment, O-ring guide 136 may be made from a metallic material. Preferably, the metallic material may be stainless steel to prevent rust build up from contact with water from the water supply.

The collet 160 may be moveable inside the inner capacity 131 between a retracted position and an extended position. Further, the collet 160 may include a cylindrical collet body 161 and a circumferential collar 162 and the cylindrical collet body 161 may include an outer collet surface 163 and an inner collet surface 164. In one embodiment, the inner collet surface 164 may include a gripping means 165 configured to positively grip the water supply tube 140 when inserted into the collet 160.

Further, an inner fitting surface 137 of the quick-connect fitting 130 body may include a stop means 135. The stop means 135 may be configured to block the gripping means 165 from moving into fitting 130 more than called for by op the device's operation and may prevent the collet 160 from falling out of the quick-connect fitting body 132 when pulled into the extended position. This may be particularly useful when the water supply tube 140 is pulled. In this example, the gripping means 165 holds its grip on the water supply tube 140 whilst it's being pulled, and the stop means 135 prevents the collet 160 and the water supply tube 140 from falling out. This may prevent unwanted disconnection of the water supply tube 140 from the quick-connect fitting 130. When a user wants to remove the water supply tube 140 from the quick-connect fitting 130 they may hold down the circumferential collar 162 of the collet 160 to hold it in the retracted position such that the stop means 135 is not engaged, and the water supply tube 140 can be pulled from a grip of the gripping means 165.

Preferably, the fill valve 100 does not comprise a coupling nut to attach the water supply tube 140 to the fill valve body 110 due to the issues that arise from the coupling nut, such as cracking of the coupling nut resulting in leaks and floods. Instead, the water supply tube 140 may be configured for connection to a water supply valve 15 at a first end 144, and for insertion into the quick connect fitting at a second end 146. The second end 146 of the water supply tube 140 may be configured for insertion into the collet 160 and held in friction within the inner capacity 131 of the quick-connect fitting body 132. As above, the gripping means 165 may hold the water supply tube 140 in friction.

The quick-connect fitting body 132, the O-ring 134, and the collet 160 may all be concentric relative to the vertical axis 105. In embodiments including the O-ring guide 136, the O-ring guide 136 is also concentric with the quick-connect fitting body 132, the O-ring 134, and the collet 160. A concentricity of the quick-connect fitting body 132, the O-ring 134 and the collet 160 (and the O-ring guide 136 in embodiments where it is included) may define a tube-passageway 152 having a passage-diameter 153 substantially equal to an outer diameter 142 of the water supply tube 140. Preferably, the water supply tube 140 may include the outer diameter 142 of 3/8 inches.
